The arrangement materially reduces and minimizes the wear on the parts of the chain as well as the bucket elements, and permits a heavier construction of the upper or double section of the chain.

shown in Figures 1 and 2 of the drawings. Mounted on the sha-ft5 and extending on each side of the power wheel 11, asshown in Figure 1,'is the rope guard 15, each arm 0'? which is provided with a shoe 16 for securing the rope within the groove of the power wheel;

A holding line 21 is connected with apin 22 mounted transversely on the upper end of the head 19. i

To the foregoing I make no claim of novelty, as the elements are all old and their 1 mode of operation is well. known. I will now proceed to describe the arrangement of the power chain which constitutes my present invention.

The drum or hub 10 is provided, on each side of the power wheel 11, with a raised portion or nub 10, which has a suitable recess or slot 10 in which the lower extremity of the single portionrof the chain is sunk and secured by the transverse pin 26 inserted in a suitable aperture through said nub 10. The upper ends of the duplex portion of the chain are pivotally connected to the equalizer bars 2i, which, in turn, are pivotally connected to suspension straps 23, the latter being pivotally 3 ipported at their upper ends to the upper center shaft 8.

The chain referred to, as it appears detached from the bucket is shown in Figure 5 of the drawings, the double section being indicated at 25 and the single section at 25.

It is so constructed that in the closing of the bucket the single section will wrap completely around the drum without overlapping, and, as the drum continues to rotate in the action of closing the bucket, the duplex section will wrap on each side of the single section of the chain without coming in contact with the latter until the bucket is closed.

In my Patent No. 906,184, of December 8, 1908, I have shown. the same chain construction, but in said patent the duplex sec tion of the chain connects with the drum, while the single portion connects with the upper suspension bars.

By the present arrangement, with the duplex portion of the chain the last to wind over the hub in the closing operation, the maximum strain, which occurs at the end of the closing movement, is now taken by the duplex or double portion of the chain, which, besides its additional element, may now be made of heavier construction.

Under the old arrangement the end links of the duplex portion of the chain were sunk into the drum into suitable slots in the hub and secured therein by transverse pins. This arrangement materially affected the size of the parts. In the present arrangement I am able to use a raised portion or nub for the end link of the single portion of the chain,

which expedient for obvious reasons would have been an impossibility for fastening the duplex ends of the chain.

Having thus described my invention what I claim is:

1. The combination of a bucket formed of a plurality of sections, mechanism for operating said sections including a power wheel having a hub portion, and a chain for opening and closing the bucket sections comprising a single section and a plural section, the single section being secured to the hub of the power wheel and adapted to make a single turn about the same, and the members of the plural section being adapted to make a single turn around said hub on either side of the single section.

2. A bucket comprising a plurality of sect'ions, a pivot about which said sections move, a power shaft connecting said sections, a power wheel, and a chain for opening. and closing the bucket sections comprising a single section and a plural section, the single section being secured to the power wheel and the plural section being suspended from said pivot.

3. A bucket comprising a plurality of sections, a pivot about which said sections more, a power shaft connecting said secdons, a. power wheel, a chain for opening and closing the said sections of the bucket comprising a single section and a plural section, the single section being secured to said power wheel and equalizing elements connected with said plural section and with the aforesaid pivot. 7

i. A bucket comprising a plurality of sections, a pivot about which said sections move, a power shaft connecting said sections, a power wheel, chains for opening and closing the bucket sections each comprising a single section and a plural section, the single section being secured to said power wheel, and equalizing elements suspended from the aforesaid pivot consisting of suspension straps pivoted at their upper ends and crossbars pivoted to the lower ends thereof and engaging the plural sections of said chains.
